ABOUT ME
Experienced React and Node.js developer (+5 years)
Experienced React and Node.js developer (+5 years)

I build AI systems and production infrastructure that solve real operational problems — not demos, but code handling voice, money, and coordination at scale. Recent work: a real-time voice and SMS AI that answers missed calls, qualifies leads, and notifies business owners autonomously; and a capital allocation protocol deployed across multiple live funding rounds.

I own technical surfaces end-to-end — architecture, system design, and shipping.
